Connection example 2: HTL encoder, unipolar, with reference signal
Figure 8-11
Because the physical transmission media is more robust, the bipolar connection should

always be used. The unipolar connection should only be used if the encoder type does not
output push-pull signals.

The photo above shows the wire jumpers for connecting unipolar HTL encoders with a
reference signal.
